I am sorry, i am talking about generally.
like for example, what will happen in this case:

if(guessp1==targetnumber) 
{ 
p1isright=false; 
} 
if(guessp2==targetnumber) 
{ 
p2isright=false; 
} 
if(guessp3==targetnumber) 
{ 
p3isright=false; 
} 
if(p1isright||p2isright||p3isright) 
{ 
System.out.println("we have a winner"); 
System.out.println("player one got it right"+p1isright); 
System.out.println("player two got it right"+p2isright); 
System.out.println("player three got it right"+p3isright); 
System.out.println("game is over"); 
} 
else
{ 
System.out.println("players will have to try again"); 
} 

will if(p1isright||p2isright||p3isright) command gets executed if atleast one of p1isright, p2isright, p3isright is false???

thanks

No.

if (a || b || c) ...

means "if a is true or b is true or c is true".

And to clarify that, because the word "or" in English is horribly ambiguous, the expression "a || b" evaluates to true if one, or both, of a and b are true. (And therefore, to false if both of them are false.)

[Raj Gurung]

OK so in example given below, if(a || b || c) command gets executed only if one of a, b or c is equal to true; even if boolean a=false, boolean b=false and boolean c=false is before if(a || b || c) conditions???

boolean a=false;
boolean b=false;
boolean c=false;
if (a || b || c)
{
statements;
}



Thanks

Have you tried it?
Do some working out with a pencil and paper and see whether any of the combinations of p q and r with the [inclusive]OR operator evaluate to true. You may find the easiest way to do that is to draw a truth table.
